ENGINEERS ORDER BULLETIN-BOARD.

SPECIFICATION forming part of Letters Patent No. 444,211, dated January 6, 1891.

Application filed April 12, 1890.

To 00% whom it may concern.-

, Be it known that I, CHARLES NV. KEMP,a citizen of the United States, residing at Charleston, in the county of Coles and State of Illinois, have invented a new and useful Improvement in Engineers Order Bulletin-Boards, of which the following is a specification.

My inventionrelates to an improvement in order bulletin -boards for locomotive-engineers.

The object of my improvement is to provide a device for displaying and for temporarily filing the written orders received by a locomotive-engineer, the arrangement being such that the immediate order under which he is running is displayed and previous orders are hidden and an alarm is sounded calling attention to the order each time the throttlelever is moved.

The accompanying drawings illustrate my invention.

Figure 1 represents a front elevation showing the bulletin board in position. Fig. 2 represents a side elevation of the same. Fig. 3 represnts a back elevation. Fig. 4 represents a central vertical section of the bulletin-board without the alarm mechanism and shows the position of the parts when an order is being placed in position to be. read. Fig. 5 represents a similar section, showing the position of the parts when an order is being filed after it has served its purpose.

A is the body of the bulletin-board, having on its back side a transverse cleat a, which is secured to a standard B, erected on the boilerhead behind and above the throttle-lever C, the arrangement being such that the board A is rigidly supported in an upright position and slightly inclined backward.

D is a narrow bar forming an extension of the board A and secured to the lower edge thereof by a spring-hinge E, which holds the bar normally with a yielding forcein the same plane as the board.

F is a heavy plate of glass, which is secured to the front face of barD by a sheet-metal band Gr or in any other suitable manner, so that the glass plate moves rigidly with the bar. Plate F is of suitable size to cover the face of board A, and the arrangement is such that the plate is held closely against the face Serial No. 847,663. (No model.)

of the board with a yielding force by the spring-hinge E.

H is a removable backing for plate F, formed, preferably, of a sheet of tin-plate having three of its edges bent forwardly at sub stantially right angles, so as to embrace the top and the vertical edges of plate F. Backing H is inserted between plate F and the board A,and its purpose is to form an opaque partition between the dead orders and those under which the engineer is running and to form a white ground against which the orders, which are usually written on tissuepaper, may be easily read. In using the bulletin-board the top of plate F is swung outward, as shown in Fig. 4, and the order y is spread against the uter surface of the tinplate backing II, and the plate F on being released holds the order closely and smoothly in place, so that it can be easily read through the glass plate. YVhen a new order is received, the old one is taken out from between plates F and H, and both plates are then swung forward, as in Fig. 5, and the old order is placed against the board A, where it is secu relyheld by spring-hinge E when both plates are released.

For the purpose of directing the attention of the engineer and his fireman to the run-- hing-order, so as to prevent its being overlooked or forgotten, I connect an alarm-bell i with the throttle-lever O in such a manner that the movement of the lever will cause the bell to be struck. This is accomplished by the following mechanism: A bracket j, having a forked baekwardly-bent arm k and a forked forwardly-bent arm Z, is secured to the back of board A. The bell t' is also secured to the board. A hammer m, having at its lower end a lug or, provided with a projecting lip 0, is pivoted in the forked arm k in such a position that the upper end of the hammer will strike the bell. A lever 19, having its outer end bent to form a double-inclined cam r, is pivoted in the forked arm 1 in such a manner that the cam 0" lies in the path of movement of the throttle-lever, the other end of the lever being extended backward and having the trip-levers pivoted thereto. Triplever .9 extends upward into the arm 70, and is provided near its upper end with a shoulder 1, which is adapted to engage the projecting lip 0 on the hammer. The trip-lever is held in contact with the back edge of ing a by a spiral spring u, having its opposite ends attached, respectively, to the lug and the lever. Spring it operates, also, to hold up the rear end of the leverp. so that cam r is thereby held down against the throttle-lever C. \Vhen the throttle-lever is drawn forward, and again when it is pushed backward, the front end of lever 19 is raised by the passage of the throt- 1 tle-lever under cam r, and trip-lever 3 being pulled downward its shoulder 2f first engages and then slips off of lip 0 on lug n and causes the hammer to strike the bell. For the purpose of preventing the ringing of the bell when there is no order a light arm r, having I a hole a, is secured to the upper side of lever J,and the lever is thereby hung upon a pin at, projecting from bar D, so that cam r is out of the path of movement of the throttle-lever, the arrangement being such that when the bar is tipped forward by the act of putting a new orderin position arm r will slide off from the pin, and the lever will without special attention be again in position to sound the bell.

By this device the running-order is kept in view where it can be easily read, while all other orders are securely taken care of, but hid from view, and the attention of the en gineer is called to the order every time he starts or steps his engine.

I claim as my invention- 1. In a bulletin-board, the combination of the board, the bar forming an extension of the board, the glass plate secured to the bar and arranged to cover the face of the board, and. a spring-hinge connecting the bar and the board and arranged to hold the glass plate against the face of the board, substantially as and for the purpose set forth.

2. In a bulletin-board, the combination of the board, the bar forming an extension of the board, the glass plate secured to the bar and arranged to cover the face of the board, the spring-hinge connecting the bar and the board. and arranged to hold the glass plate against the face of the board, and the opaque backing-plate arranged between the glass plate and the board,all arranged to cooperate substantially as set forth.

3. The combination of the bulletin-board adapted to hold and display an ordersheet, the throttle-lever, the bent lever pivoted to the bulletin-board and arranged with its free end in the path of said throttle-lever, the hell, the hammer arranged to strike the bell, and intermediate connecting mechanism connecting the bent lever and the hammer, all arranged to co-operate substantiallyas spcci fled, whereby the act of moving the throttle-lever operates to strike the bell and to call attention to the bulletin-board, as set forth.
